OZONE

Moving on into the environment side of politics, scientists have noted that the o-zone is beginning to recover. This has largely been due to the phase out since the 1908's; items such as aerosol cans and certain chemicals used in refrigerators have been the main focus.
As reported by Ten News, scientists were able to confirm a statistically significant increase in stratospheric ozone, which sheilds the planet from solar radiation that causes skin cancer and other problems (Ten News, 2014)

The United Nations, according to the Australian, informs that by 2030 there would have been an extra 2 million skin cancer cases a year around the world if ozone problem has not been stressed years ago. NASA scientist Paul A. Newman, claimed that the heat-trapping greenhouse gases - considered the major cause of global warming - are also helping to rebuild the ozone layer, (The Australian, 2014) The report said rising levels of carbon dioxide and other gases cool the upper stratosphere, and the cooler air increases the amount of ozone.

The ozone layer is still far from healed. The long-lasting, ozone-eating chemicals still lingering in the atmosphere create a yearly fall ozone hole above the extreme Southern Hemisphere, and the hole hasn't closed up. Also, the ozone layer is still about 6 percent thinner than in 1980, by Newman's calculations.

This highlights that when the world comes together and attempts to make a change, a great impact can result. I think that it is important for people to be continually aware of the environment; keeping up with the statistics and finding ways to make small changes to our lifestyle to make a cleaner future.
